I'll tell you this much: Waffa Bilal, the dude who attached a camera to the back of his head, is pretty dedicated to this ridiculous art project of his. Surgeons recently needed to remove some pieces in his head because his body rejected one of the three titanium posts implanted there. He's still planning on continuing the project and currently tying a camera to the back of his neck as his wound heals. Not sure why he just didn't do that from the start. [Chronicle via Pop Sci]
